5-42. The boom supports the two vertical loads. Neglect the size of the collars at D and B and the thickness of the boom, and compute the horizontal and vertical components of force at the pin A and the force in cable CB. Set F₁ 800 N and F2 = 350 N. 5-43. The boom is intended to support two vertical loads, F1 and F2. If the cable CB can sustain a maximum load of 1500 N before it fails, determine the critical loads if F₁ =2F2. Also, what is the magnitude of the maximum reaction at pin A? 1.5 m 4 1 m B D F₂ A 30° F1 Probs. 5-42/43
